“I’ll have to take out my rain boots”… ‘Autumn rainy season’ under the influence of Typhoon Haiku

At 9 am on the 28th, the Korea Meteorological Administration announced that the 11th typhoon ‘Haikui’ occurred in the sea 570 km north-northwest of Guam.

The central air pressure of Haiku is 998 hPa (hectopascal), and the maximum wind speed is 18 m/s (65 km/h).

Haikui, which is moving west-northwest at 14 km/h, is expected to move to the sea 150 km southwest of Okinawa, Japan around 9:00 am on the 2nd of next month.

As it has not been long since it developed into a typhoon, the variability is high.

The Korean Numerical Forecasting Model ( KIM ) predicts that Haikui will move to the southern seas of Japan, but the European Medium-term Forecasting Center (ECMWF) model ( ECMWF ) predicts that it will move toward Shanghai, and the United Kingdom Meteorological Administration ( UM ) model predicts that it will land inland in southern China via Taiwan. forecasted

Haikui is the name submitted by China to the Typhoon Commission and means sea anemone. Typhoon names are written sequentially from 110 words submitted by 14 member countries of the Typhoon Committee.

The rain that fell sporadically across the country on the 28th will continue until the 29th.

As of 10:00 a.m., a heavy rain warning was issued in some areas along the southern coast of Jeollanam-do, and very strong rain fell around 30 mm per hour. It is raining in the Jeolla region, the metropolitan area, the middle and northern parts of Gangwon, Chungnam, the western part of Gyeongnam, and Jeju Island.

The rain is coming as a result of a low pressure that developed in the inland of southern China the previous day.

The low pressure developed in the interior of southern China the previous day is now located in the southern part of the Shandong Peninsula. This low pressure is expected to move northeast, pass over the West Sea, and pass through North Korea.

Heavy rain will fall along the path as the low pressure blows in warm, moist air. A lot of rain is expected, especially in areas where the wind collides with the terrain, as warm and humid air flows in from the south as well.

After the low pressure escapes to Maritime Province on the 30th, relatively cold and dry air moves southward, forming a boundary with the high-temperature and humid North Pacific high pressure that has expanded westward, creating a stagnant front, and heavy rain is expected.

It is unclear how long the ‘secondary rainy season’ or ‘autumn rainy season’ will last and which regions will be affected.

Typhoon No. 9 ‘Saola’, Typhoon No. 10 ‘Damrei’, and Typhoon No. 11 Haikui are active at the same time, and tropical turbulence (atmospheric flow in tropical areas where low pressure is expected to develop) continues in the low-latitude sea in the south of Korea. As it develops, the barometer volatility is large.

However, Saola and Damrei are not expected to affect Korea.

An official from the Korea Meteorological Administration explained, “The Korea Meteorological Administration does not officially mention the second rainy season or the autumn rainy season.” “Since the typhoon is a complex pattern in the south of Korea, there is high variability in how long and where the congestion front will affect.” .

The estimated cumulative precipitation for the 28th to 29th is 30 to 80 mm in the metropolitan area, Gangwon-do, and Chungcheong areas, 50 to 120 mm in the Jeolla and Gyeongsang areas, 30 to 100 mm in Jeju Island토토사이트,

In the eastern part of Jeonnam, the western part of Gyeongnam, Jeju Island, and the 5th West Sea, it will come up to 150 mm.

There is a possibility that the storm warning issued on the 28th, centered on the far sea of ​​the West Sea, will expand from the morning of the 29th to the west sea offshore, and from the night to the far sea in the central east sea.

From the afternoon of the 28th, swell waves will flow into the coast of Jeju Island, where warm air flows in, and from the 29th, there is a possibility of flooding in the west and south coasts due to sea level rise caused by low pressure.
